HVL Voltage Limiting Device
The HVL is a combination of a metal oxide (MO) surge arrester without gaps and a low voltage limiter. The MO-surge arrester is realised by a MO-varistor, the low voltage limiter is realised by two anti-parallel connected thyristors. The MO-varistors and the low-voltage limiter are connected in parallel.
Overvoltages generated by lightning with a time duration of some ten microseconds are limited by the MO-varistor. Overvoltages with a time duration of 0,4 ms and longer will be limited by the thyristors to a voltage below 3 V. The HVL is completely moulded in silicon.
